Lesson 55 Not a gold mine
'The Revealer' is a new machine which is used for detecting buried gold. Using this machine, a research party recently tried to find gold in a cave near the seashore. Although they examined the cave thoroughly they only found a small gold coin which was practically worthless. However many people
believe that the machine many reveal something of value soon.
Lesson 56 Faster than sound
A lot of old cars entered for the race, which is held once a year. A great many loud explosions could be heard when they set off and though many cars broke down during the race, a few managed to complete
the course. The winning car went downhill so quickly that its driver had a lot of difficulty trying to stop it.
Lesson 58 A blessing in disguise
The number of visitors to the village of Frinley has increased because there is said to be a ‘cursed
tree’ near the church. Since the villagers believe that if anyone picks a leaf he will die, they have asked the vicar to have the tree cut down. As the tree is a useful source of income, the vicar has refused to have the tree cut down. Meanwhile, though tourists have been picking leaves, not one of them has come to harm.
Lesson 59 In or out ?
Our dog, Rex, used to sit outside the front gate and bark so that someone would open it. Ever since my
husband trained him to open the gate himself, Rex has developed another bad habit. He barks when he
is in the garden so that someone will let him out. After this he lets himself in and barks until someone opens the gate again. Now that my husband has removed the gate, Rex has disappeared.
Lesson 60 The future
The writer visited a fortune-teller at a village fair who told him that a relation was coming to see him. She added that a woman he knew well would speak to him when he left the tent and he would follow her out of the fair. This came true because his wife spoke to him when he went outside. She told him they had to meet his sister at the station and she led him out of the fair.
Lesson 61 Trouble with the Hubble
When the Hubble telescope was launched into space in April 1990, the pictures it sent us were very
disappointing because the main mirror was faulty. Four astronauts will soon be making the necessary
repairs, and eventually, pictures from the Hubble will tell us a great deal about the age and size of the universe.
Lesson 62 After the fire
It took the firemen nearly three weeks to get the forest fire under control. Now that all the great trees had been burnt, there was danger that heavy rain would cause serious floods which would destroy the surrounding villages. To prevent this, the forest authorities ordered grass-seed which was sprayed over the ground by planes for nearly a month. By the time that it began to rain, the grass had taken root in many places.
1. b
根据课文第8-9行…but so far he has refused. He has pointed out that the tree is a useful source of income 可以判断只有c. it earns money 与课文的实际内容相符，是牧师拒绝把树砍掉的原因，其他3个选择都与课文的实际情况不符，所以选b.

3. a
该句缺少主语和谓语，只有一个that引导的从句。只有a. They say (他们说，人们说)，最适合这个句子，也合乎语法和习惯用法。其他3个选择b. it said (它说)意思不对，应该是it is said 才正确；c. Said 缺少主语；d. It is saving 不合乎习惯用法，应该是It is said 才对。

Lesson 56:Faster than sound! 比声音还快！
Once a year, a race is held for old cars. A lot of cars entered for this race last year and there was a great deal of excitement just before it began. One of the most handsome cars was a Rolls-Royce Silver Ghost. The most unusual car was a Benz which had only three wheels. Built in 1885, it was the oldest car taking part. After a great many loud explosions, the race began. Many of the cars broke down on the course and some drivers spent more time under their cars than in them! A few cars, however, completed the race. The winning car reached a speed of forty miles an hour -- much faster than any of its rivals. It sped downhill at the end of the race and its driver had a lot of trouble trying to stop it. The race gave everyone a great deal of pleasure. It was very different from modern car races but no less exciting.
句子讲解：
本文语法：复习级和比较级及数量词的用法 (参考Lesson 8和Lesson 32的语法分析。
1. c
根据课文第一句和最后一句Once a year, a race is held for old cars. It was very different from modern car races but no less exciting 可以推测只有c. All the cars were old 是汽车比赛不寻常之处，其他3个选择虽然都是课文所提及的内容也与汽车比赛有关，但它们都不能清楚表明汽车比赛为什么不寻常。
2. a
根据课文第8行A few cars, however, completed the race 只有a. but only a few completed the course 与课文的实际情形相符，其他3个选择都与课文的实际情况不符。
3. c
只有c. lots of 与前一句中的 A lot of (很多)的意思相同，所以应该选c。a. much 不能修饰可数名词；b. lot of 不是正确的表达方式，应该是a lot of 或者lots of ； d. plenty (充足)， plenty of 是一个短语，表示“足够的”，而且这个短语也不符合题目意思。
